Operate with the principle of least privilege

In many examples of malware infection, the malware may only function using the privileges of the logged-in user. To lessen the effect of malware infections, think about using a standard or restricted user account (i.e., a non-administrator account) for day-to-day activities. Only log in with an administrator account—which has full operating privileges on the system—when you need to install or remove software or change your computer’s system settings.
